currently i am learning microcontroller in proteus, i am found out it can write the source code in .asm change to .hex and put in to the microcontroller to simulate. but i can't do it.

can someone tell me step by step how to change this code to .hex

;******Set up the Constants*****
STATUS equ 03h  ;Address of the STATUS register
TRISA equ 85h  ;Address of the tristate register for port A
PORTA equ 05h  ;Address of Port A
COUNT1 equ 08h  ;First counter for our delay loops
COUNT2 equ 09h  ;Second counter for our delay loops
;******Set up the port******
 
  bsf STATUS,5 ;Switch to Bank 1
  movlw 00h  ;Set the Port A pins
  movwf TRISA  ;to output
  bcf STATUS,5 ;Switch bank 1 to bank 0
;******Turn the LED on*****
 
Start  movlw 02h  ;Turn the LED on by first putting
  movwf PORTA  ;it into the w register and then on the port
;*****Start of the delay loop 1****
Loop1  decfsz COUNT1,1 ;Subtract 1 from 255
  goto Loop1  ;If COUNT is zero, carry on
  decfsz COUNT2,1 ;Subtract 1 from 255
  goto Loop1  ;Go back to the start of our loop
;*****Delay finished, now turn the LED off*****
  movlw 00h  ;Turn the LED off by first putting
  movwf PORTA  ;it into the w register and then on
;*****Add another delay*****
Loop2  decfsz COUNT1,1 ;This second loop keeps the
  goto Loop2  ;LED turned off long enough for
  decfsz COUNT2,1 ;us to see it turned off
  goto Loop2  ;
;******Now go back to the start of the program*****
  goto Start  ;go back to the Start and turn LED
;******End of the program*****
end     ;Needed by some compilers

Please help me

 

Hello,

The program you are showing needs to be compiled.
During compiling the .asm file gets converted to a .hex file.
The compiler must know for wich pic the program has to be compiled.
This compiling can be done by microchips program MPLAB.

hi
what is the asm file for and what does it do ?

 

It is a set of instructions for the microprocessor. An assembler lets you generate a program using commands that are reasonably close to English. The editor function lets you write the instructions. The assembler proper parses the instructions and outputs the actual machine code.

If you follow the comments (the text to the right of the with an instruction set list for the microprocessor, you can tell what the program is supposed to do.

I do not know what microprocessor is associated with the instructions.
